Abstract
We prove the existence of solutions to the static contact problem with Coulomb friction, provided that the coefficient of friction is small enough. The proof employs the penalty method and a certain smoothing p rocedure for the friction functional. Using optimal trace estimates fo r the solutions of the Lame equations, we calculate an upper bound for the admissible coefficient of friction which is greater than the corr esponding bounds proposed by Necas, Jarusek and Haslinger (1980) and b y Jarusek (1983).
